Letters Patent No. 90,330, dated May 18, 1869.

.IMPROVE'D REVERSIBLE HINGE.

The Schedule referred to in these Letters Patent; and making of thesame.

-To all whom it may concern Be it known that I, H. J. WOLTERS, of Salem,in the county of Essex, and State of Massachusetts, have invented a newand useful Reversible Hinge; and I do hereby declare the following to bea clear and exact description vof the nature thereof, sufficient toenable others skilled in the art to which my invention appertains, tofully understand and use the same, reference being had to theaccompanying drawings, making part of this specication, Yin which-Figure l is a front view of a portion of a door or shutter, having myhinge applied thereto.

Figure 2 is a front View of the hinge fully opened.

Figure 3 is a top view thereof.

Figure 4 is a view of the friction-box.

Similar' letters of reference indicate corresponding parts in theseveral figures. y

My invention consists in a hinge, which is readily reversible to-a rightand left-hand door or shutter, and operates with but little friction.

In the drawings- A represents the leaves of a hinge, each of which isformed with a socket, B, the openings of which, when in position on thedoor or shutter and frame, will face each other.

C represents` the friction-boxes or pintles, each of which consists oftwo cones a a, jointed at their bases, with a disk or shoulder, b,between them.

The cones are adapted to enter the sockets, and move readily therein.

The shoulders form part of the bearing-surfaces of the hinge, and, whenin position, are between the sockets, as seen in figs. 1 and 2.

Besides this, the sockets are closed at one end, and form cups toreceive and retain oil for lubricating-purposes. Owing to the shape oftheir outer faces, water finds no lodgment on the upper ones, and cannotenter the lower ones in consequence of the washer of the pintle.

It will be perceived that the hinge is readily adapted for right andleft doors or shutters, by merely changing the location of the leaves.

The friction-boxes or pintles correspond with all the sockets, and enterand receive either of them.

The hinges work with comparatively little friction. They allow doors andshutters to open and close to their full extent, and for large buildingswill be found exceedingly useful. rlhey are alike simple and practical.

I am aware that it is not new to construct a removable pint-le, having acentral washer, nor is a reversible hinge new iu itself, and I thereforedo not claimA them; but having thus described mynventlon,

What I claim as new, and desire to secure by Letters Patent, is

The hinge, consisting of the two closed Aconical sockets B, and thedouble-conical pintle c a., with washer b, when constructed to operatetogether as described.,

To the above l have signed my name, this 28th day of April, 1869.

. H. J. WOLTERS.
